DISPLAY AND DISPENSING DEVICE.

Specification. of Letters Patent.

Patented June 28, 191W.

Application filed June 23, 1915. Serial N 0. 35,856.

To all whom it may concern Be it known that I, ALIoK O. BERGMAN, a citizen of the United States, residing at Milaca, in the county of Millelacs and State of Minnesota, have invented new and useful Improvements in Display and Dispensing Devices, of which the following is a specification.

This invention relates to display and dispensing devices and more particularly to a structure for displaying and dispensing screen fabric.

One of the principal objects of the invention is to provide a simple and efficient device of this character in which a large num ber of screen rolls may be supported for convenient display or dispensing and wherein the screen as dispensed is measured.

A further object of the invention is the provision of a screen rack having novel means for holding the same against retrograde movement when anyone of the screen rolls is unrolled for display or dispensing and further means for holding the end of the screen roll exposed and in position for the operator to grasp in drawing out of the rack.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawings which form a part of this application, and in which Figure 1 is a side elevation of the device,

Fig. 2 is a top plan view thereof,

Fig. 3 is a detail horizontal sectional view,

Fig. 4 is a detail vertical sectional view taken on the line 4-4 of Fig. 2, and

Fig. 5 is a transverse section on the line 55 of Fig. 1.

Referring more particularly to the drawing, the supporting frame of the device comprises four uprights 1 and 1*, connected together adjacent their lower ends by the crosspieces 2 and 3 and at their upper ends by the side members 4 and shear supporting bar 5. The rear uprights 1 extend some distance above the side members 4 and are connected together at their upper ends by a cross-piece 6. As shown, there is mounted in and extending between the side members 4 a shaft 7 upon which is journaled the screen drum generally indicated at 8. This drum comprises side plates 9 having a plurality of apertures 10 formed therein, the side plates being connected by a cylinder 11 in which is supported by the side plates, a plurality of roll receiving tubes 12. These tubes or cylinders 12 are slotted at one side so as to register with similar slots 13 formed in the cylinder 11, thus providing an exit for the fabric carried within the tubes 12.

Extending across each slot 13 and journaled in the side plates 9 are cam rods 14 normally actuated by torsion springs 15 to bind against one wall of the openings 13 to bind the fabric against said Wall as will be readily understood from an inspection of Fig. 4.

In order to prevent retrograde movement of the drum or rotary rack, there is secured to the uprights 12 a pair of spring arms 16 curved upon their outer ends to fit the arc of the openings 10 and each being provided with a limiting stop 17 which limits the inward movement of their free end when the next lower roll is in position to have the fabric drawn therefrom for sale. This spring arm acts in the capacity of a pawl and the walls of the openings 10 act in the capacity of a ratchet.

The shear bar 5 preferably carries a pivoted shear blade 18 operating in conjunction with a stationary shear blade 19 in the bar 5 and forward of the shears is a measuring roll 20 journaled in the side pieces 4 and adapted to measure a foot of fabric for each complete rotation thereof as the fabric is wound upon the winding roll 21 operated through a crank 22.

In the operation of the device a roll of screen fabric is inserted in each tube or cylinder 12 with its end projecting through the slot 13 between the cam rod and one wall of the slot 18, the spring 15 acting to bind the fabric between the cam rod and the wall of the opening so as to prevent inward movement of the free end of the fabric. By grasping the fabric and pulling upon the same, the cam rod will be automatically released and when the fabric is severed the cam rod will automatically act to bind the fabric against the wall of the opening thereby holding the end exposed in position to be grasped by the operator when desired. As the fabric is pulled out from the opening 13, it is passed between the shear blades 18 and 19, over the roll 20 and attached in any suitable manner to the roll is then operated to wind the fabric upon the roll 21 which, as shown, is removably mount- 21. The crank ed in the jendsof the side pieCe 4 0 t at. after the fabric has been wound thereon and severed by the shear blades, the roll 21 lar series of tubes connecting the side platesandbeing-slotted: to register with the slots in the cylinder, said side plates having openings leading into the :tubes, and a spring arm lnterposed between the frame and said side plates, having one end secured to said frame, and the opposite end being ofiset defining a shoulder for engagement with the Copies 50f this patent may be obtained for live cents each, by addressing the f-f,0ommisS Q '.-0 nts walls. of saith openings for preventing retrograde movement.

2. In device of the class described, a frame, a shaft mounted in the frame, a drum journaled upon the, shaft and comprising in part apertured" side plates and a slotted cylinder rollreceiving members extending between the side plates and registering with the openings,.a cam-shaped rod extending across and within the slots of the cylinders for automatically grippingthe fabrio against-onewall of the slot, thereby preventing rewinding of the fabric on the roll. 1

In testimony whereof I affix my signature I in presence of two witnesses.
